Founders often ask me whether they should file a patent or simply keep their idea confidential. There is no single right answer. The two routes protect innovation in almost opposite ways, and the better choice depends on what you have built and how you plan to use it.
What a patent actually gives you
A patent under the Patents Act, 1970 grants a limited monopoly, usually twenty years from the date of filing, in exchange for publicly disclosing how the invention works. After that period the invention belongs to everyone. To qualify, it must be new, involve an inventive step, and be capable of industrial application. Software as such, business methods, and mere discoveries are generally excluded under Section 3.
What a trade secret gives you
A trade secret has no registration and no expiry. It lasts only as long as the information stays secret. The classic example is a recipe or a manufacturing process. India does not have a dedicated trade secret statute, so protection comes from contracts, confidentiality clauses, and the law of breach of confidence.
How I usually frame the decision
If a competitor can reverse engineer your product the moment it reaches the market, secrecy will not hold and a patent makes more sense. If the innovation lives inside your factory and cannot be seen from the outside, a trade secret may protect it for far longer than any patent would. Cost, timeline, and your appetite for disclosure all matter too.
Whatever you choose, decide early. Demonstrating an invention before filing can destroy its novelty, and a leaked secret is almost impossible to claw back.
